What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

Researchers at Children's Hospital Los Angeles are testing a prototype wearable stethoscope that records lung sounds in children and adolescents with asthma aged 4 to 17. The study compares the device's recordings with those from a standard digital stethoscope to see if it can accurately detect abnormal lung sounds and changes after bronchodilator treatment. The goal is to determine whether the wearable device can help assess asthma control and potentially offer a convenient way to monitor the condition.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A prototype wearable stethoscope, a wireless device that records lung sounds in children with asthma
What this could lead to
If it works, this could lead to a simple, wearable way to monitor asthma control at home and catch changes early.
What could go wrong
This is an early, small study of 50 children, and the device may not match the accuracy of standard stethoscopes or reliably reflect asthma control.
